This invention relates to the oflicial class of cutlery and more particularly to a razor and shear sharpener.

The primary object of this invention resides in the provision of a sharpener of such construction that a keen and smooth edge can be formed on razors or shears by barbers and others with little effort and in a short period of time.

Another object of this invention resides in the provision of a sharpener for razors, shears and the like whereby the cutting edges thereof will be properly disposed against the sharpener for forming a keen and smooth cutting area thereon.

A further object of this invention resides in the particular construction and arrangement of the guide relative to the sharpening portion of the sharpener.

With these and other objects in view, this invention reside in certain novel features of construction and arrangement of elements to be hereinafter more particularly set forth in the specification, illustrated in the accompanying drawing and pointed out in the appended claims and, while this disclosure depicts my present conception of the invention, the right is reserved to resort to such changes in construction and arrangement of elements as come within the spirit of the invention.

In the accompanying drawing forming a part pf this application:

Fig. 1 is a perspective view of the sharpener.

Fig. 2 is an enlarged sectional view taken approximately on line 22 of Fig. l.

Fig. 3 is a sectional view of a modified form of the sharpener.

In the present illustration of this invention the numeral 5 designates, in general, a razor and shear sharpener preferably constructed of steel having a substantially smooth surface but which may be provided with a surface of any well known abrasive character such as is used in sharpening and grinding cutlery and other edged instruments. v

The sharpener 5 is preferably of substantially rectangular configuration at that end thereof indicated by the numeral 6 and merges into a substantially conical portion indicated by the numeral 1 the surfaces of which. acting as rubbing areas against which the cutting edges of razors, shears and the like are disposed to form keen and smooth cutting tools, instruments of the cutlery classification.

Formed on the smaller end of the aforesaid conical portion of the sharpener is a. stud 8 provided with threads to threadedly engage a threaded boss 9 formed on the outer side of an arcuate guide I 9. Said guide It is curved inwardly to somewhat overhang a portion of the smaller end of the conical portion I and thereby form a channel for the reception of the back portion of a razor blade B so as to dispose the edge thereof in proper contact with the surface of said portion 1 to form a keen and smooth area thereon throughout its entire length and also to permit manipulation of the razor over said portion 1 in a rapid and safe manner. The blade B is herein illustrated as having a handle-R but may be otherwise sharpened with the handle removed if desired.

The surface of that portion of the sharpener indicated by the numeral 6 is utilized to form keen and smooth edges on shears, cutlery and the like as well as formin a handle when sharpening razors.

Although the sharpener is herein recited as being formed from a steel rod having the configurations set forth, it is to be understood it can be constructed from any well known material capable of performing similar function or may have its surfaces roughened or otherwise treated to permit either fine or coarse grinding, smoothing or the like whereby proper edging of the cutting tool, instrument or the like can be procured. Further, the portion of the sharpener indicated by the numeral 1 may be of rectangular configuration in cross section and tapered throughout its length similarly to that shown in the drawing, in fact, the cross section configuration of the sharpener may be of any desired form capable of carrying out the salient features of this invention when used to sharpen tools, instruments and the like of various kinds.

In Fig. 3 of the drawing the guide I!) is provided with a smooth aperture lit for loose reception of the threaded stud 8 and, in order to adjust and retain said guide in elected positions relative to the conical portion I so as to permit the blade B to be rubbed against various portions of the surface thereof, a thumb nut l I is screwed on the stud 8. On occasions where the operator desires the razor blade to rotate around the rod with its back edge resting against the guide: 10, the thumb nut II is loosened.

Having thus described my invention it is manifest that a sharpener is provided which is simple in construction and which permits precision edging of cutlery of various kinds and, through the assemblage of but few elements, the cost of manufacture is such that the same can be sold at a reasonable price.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A razor and shear sharpener comprising, a hard metal rod'having a portion thereof of substantially rectangular configuration with one end merging into a substantially frusto-conical poron the smaller end of the frusto-conical portio and an elongated guide carried by the stud.

3. IA razor and shear sharpener comprising, a rod having one end of substantially frusto-conical configuration, a stud formed on the smaller end of the frusto-conical portion of the rod, and an inwardly curved substantially rectangular guide mounted on the stud.

4. A razor and shear sharpener comprising, a

steel rod having a substantially smooth surface and a tapering end portion, a stud formed on the smaller free end of the tapering portion of the rod, and an inwardly curved guide mounted on the stud.
